just because he was under center and making plays doesn't mean he was effective at reading defenses.
he could have been given a simple 1 or 2 read and run if they're not open option.
and playing under center in the red zone doesn't really count either since the defense is limited in what it can do.
True it's possible that he could have been given 1 or 2 reads per play under center, but that wasn't the case - you can watch his youtube highlights if you don't have game film. That's what I had to do.
And even if that were true, our RBs are in better position to be effective and comfortable receiving quicker handoffs from the QB. Defenses would be forced to account for Williams and Stewart again. So, an offensive scheme switch isn't just about Cam. It would help put our other backs in position to make plays.
